PROPRIETARY CarTech HyMu 800 Alloy Heat Treatments

  • Annealing
    In-Process Anneal:
    In-process annealing for further cold rolling of strip products should consist of a strand annealing operation in a nonoxidizing, noncarburizing atmosphere (dry hydrogen or NH3 preferred) at 1000/1050°C (1830/1920°F) that will produce a tensile strength of 690 MPa (100 ksi ) maximum.
    Thermal Treatment for Magnetic Properties:
    Specific magnetic characteristics are obtainable through selection of the thermal treatment used; low temperatures 732/843°C (1350/1650°F) for very high frequency response, and high temperatures 1120/1177°C (2050/2150°F) for low frequency response.
    HyMu "800" should be annealed in an oxygen-free, dry-hydrogen atmosphere with a dew point below -40°C (-40°F). For uniformity of properties, material should be held 2 to 4 hours at temperature and cooled at a rate of 167/333°C (300/600°F) per hour through the order-disorder range 649/427°C (1200/800°F).
    Oil, grease, lacquer and all other contaminants must be removed before annealing. The individual parts should be separated by an inert insulating powder such as magnesium or aluminum oxide during hydrogen annealing.
